  • The research has the purpose to study the effect of the addition of banana stem fiber as filler to the mechanical properties of composites with a matrix of Recycled Polypropylene (RPP). Banana stem fiber made of banana cut into 20 centimeters then soaked in hexane and Sulfuric Acid (H2SO4) and boiled with Sodium Oxide(NaOH) for 1 hour, the purpose to remove dirt and grease as well as lignin present. After that enter into the oven for 10 hours at a temperature of 80 degrees and then combed up into fibers. Banana stemfiber compositesmade with amoldsize of20x15centimetersandpressedbyHot Pressat a temperature of200 degreespressure of2bar, for 30minutes.
